Correct specification. Professional winding bars. Balance test before the opener is reconnected. Every spring repair guaranteed in Sweet Home. Do not run the opener after a spring snap in Sweet Home, OR.
The door feels heavier than it used to when you lift it manually in Sweet Home — the spring is losing tension and the door weight is progressively shifting to the opener, the cables, and your effort in Sweet Home, OR. The opener strains audibly and the door moves more slowly than it should in Sweet Home — the spring isn't providing its full counterbalancing force and the opener is compensating with every cycle in Sweet Home, OR. Or a spring snapped — you heard the bang and the door won't move in Sweet Home. Call Herlihy Garage Doors now for same-day spring repair throughout Sweet Home, OR in Sweet Home. Do not run the opener and do not attempt to manually lift the door after a spring snap in Sweet Home, OR.
Garage door spring work is the most safety-critical service in the garage door industry for a specific reason in Sweet Home. A residential torsion spring stores several hundred foot-pounds of rotational energy when wound to operating tension in Sweet Home, OR. That energy is released in a controlled way when the door opens through the spring's correct unwinding in Sweet Home. It releases in an uncontrolled way when a tool slips from the winding cone during spring replacement in Sweet Home, OR. The winding cone has four holes designed for professional winding bars of a specific diameter in Sweet Home. A winding bar that fits these holes correctly maintains contact throughout the winding process in Sweet Home, OR. An improvised tool — a screwdriver, a piece of rebar, anything that doesn't fill the hole correctly — can slip out of the cone at any point in the winding process in Sweet Home. When it slips, the stored energy releases instantly and the cone rotates at high speed in Sweet Home, OR. The improvised tool becomes a projectile in Sweet Home. This is not a theoretical risk in Sweet Home, OR. It's the mechanism behind the serious injuries that occur from DIY spring replacement every year in Sweet Home.
Herlihy Garage Doors repairs and replaces garage door springs throughout Sweet Home, OR in Sweet Home. The correct specification is measured from the specific door configuration before any spring is selected in Sweet Home, OR. The replacement spring is wound to the correct turn count for the specific door height and cable drum in Sweet Home. The balance test confirms the specification is correct before the opener is reconnected in Sweet Home, OR. Same-day service available throughout Sweet Home in most cases in Sweet Home, OR. And every spring repair is guaranteed in Sweet Home.
A spring replaced with an incorrect specification — wrong wire diameter, wrong inside diameter, or wrong length — produces a door that's either oversprung or undersprung regardless of how correctly it's wound in Sweet Home. An oversprung door can behave dangerously under manual operation in Sweet Home, OR. An undersprung door adds abnormal load to the opener motor, drive gear, and cables on every cycle in Sweet Home. Neither produces the correctly balanced door that every other component in the system depends on in Sweet Home, OR. Herlihy Garage Doors measures the correct specification before any spring is selected in Sweet Home.
The spring specification determines the door's balance in Sweet Home, OR. The door's balance determines the load the opener, cables, and rollers operate under in Sweet Home. Every component in the door system performs correctly when the spring is correctly specified and performs under abnormal load when it isn't in Sweet Home, OR. The spring specification is the foundation variable from which everything else in the system's performance follows in Sweet Home.
A torsion spring is mounted on a steel shaft directly above the garage door opening in Sweet Home, OR. When the door closes, the cables pull down on the cable drums, rotating the shaft and winding the spring tighter in Sweet Home. The winding stores rotational energy in the spring coil in Sweet Home, OR. When the door opens, the spring unwinds and releases that stored rotational energy through the shaft and drums, lifting the cables and the door in Sweet Home. The spring is wound to a specific tension that produces a lifting force equal to the door's weight at the cable drum attachment points in Sweet Home, OR. This counterbalancing force is what makes a 200-pound garage door movable with 10 to 20 pounds of net force from the opener in Sweet Home.
Extension springs run horizontally along the upper track sections on each side of the door in Sweet Home. They store energy by stretching rather than rotating in Sweet Home, OR. When the door closes, the springs extend and store energy in their stretched length in Sweet Home. Extension springs can break with significant lateral movement because the stored energy is released along the spring's length rather than through a shaft in Sweet Home, OR. Safety cables threaded through the center of each extension spring are required to contain a broken spring and prevent it from becoming a projectile in Sweet Home. Herlihy Garage Doors inspects and installs safety cables on every extension spring service in Sweet Home, OR.
Wire diameter determines how much energy the spring stores per turn in Sweet Home, OR. A heavier wire diameter stores more energy per turn than a lighter one in Sweet Home. Inside diameter determines which shaft size the spring fits on in Sweet Home, OR. Length determines the total number of active coils and therefore the total energy storage capacity in Sweet Home. All three must be correct for the spring to produce the correct counterbalancing force for the specific door when wound to the correct turn count in Sweet Home, OR.
A spring with the correct inside diameter and length but a wire diameter one gauge too light stores less energy per turn than needed in Sweet Home. Winding it to the correct turn count produces insufficient lifting force in Sweet Home, OR. The door is undersprung in Sweet Home. A spring with the correct wire diameter and inside diameter but a length that's too short has fewer active coils in Sweet Home, OR. Each coil must be wound tighter than designed to produce the required energy storage in Sweet Home. The spring is more likely to fail before its rated cycle life in Sweet Home, OR.
Herlihy Garage Doors determines the correct spring specification through measurement of the existing spring where intact, or through calculation from the door's measured dimensions and construction characteristics where the spring has failed in Sweet Home, OR. Door height and cable drum size determine the correct winding turn count in Sweet Home. Door weight estimated from size, steel gauge, insulation type, and window configuration determines the correct wire diameter and length in Sweet Home, OR. The specification is calculated, not estimated in Sweet Home.
A standard residential torsion spring for a 200-pound garage door stores approximately 300 to 400 foot-pounds of rotational energy when wound to operating tension in Sweet Home, OR. Three hundred foot-pounds is the equivalent of a 150-pound weight dropping two feet in Sweet Home. That energy is stored in the spring coil as rotational tension on a steel shaft in Sweet Home, OR. When released correctly during spring replacement, it simply unwinds the spring back to the neutral state in Sweet Home. When it releases suddenly during a tool slip, it releases all at once through the winding cone in Sweet Home, OR.
The winding cone has four holes sized for professional winding bars of a specific diameter in Sweet Home. Professional winding bars are 18 to 24 inches long and the correct diameter to fill the winding cone holes with minimal play in Sweet Home, OR. The length provides leverage and clearance in Sweet Home. The correct diameter fit prevents the bar from shifting in the hole during winding in Sweet Home, OR. Any movement of the bar in the hole during winding is a slip hazard in Sweet Home.
An improvised tool that's too narrow to fill the winding cone hole can shift in the hole during winding in Sweet Home, OR. When it shifts far enough to exit the hole, the stored rotational energy in the spring releases through the winding cone in Sweet Home. The cone rotates rapidly in Sweet Home, OR. The tool that was in the hole becomes a projectile in Sweet Home. The person holding the tool, whose hands were near the winding cone, is in the path of both the rotating cone and the released tool in Sweet Home, OR. This mechanism produces the serious hand and arm injuries that occur from DIY spring replacement in Sweet Home.
Understanding the correct procedure for spring replacement and executing it correctly under real installation conditions are different things in Sweet Home. Professional technicians have performed the winding procedure under training supervision and accumulated the repetitions that produce correct automatic body positioning in Sweet Home, OR. Correct positioning keeps the technician's body out of the path of energy release throughout the winding sequence in Sweet Home. That positioning is as important as the correct tools in Sweet Home, OR.
Herlihy Garage Doors technicians carry professional winding bars sized for the winding cones on common residential torsion springs in Sweet Home, OR. They follow correct winding procedures that maintain safe positioning relative to the spring and winding cone throughout the winding sequence in Sweet Home. They've accumulated the training repetitions that make correct positioning automatic in Sweet Home, OR.
A spring that's losing tension provides less counterbalancing force than the door weight requires in Sweet Home, OR. Disconnecting the opener and manually lifting the door reveals a door that's noticeably heavier than it was in Sweet Home. This progressive increase in felt weight is the spring's tension loss accumulating cycle by cycle in Sweet Home, OR.
A spring that isn't fully counterbalancing the door transfers the uncounterbalanced weight to the opener motor on every opening cycle in Sweet Home. The motor runs at a higher load than designed in Sweet Home, OR. It produces more heat. It accumulates wear faster in Sweet Home. The door moves more slowly because the opener is doing significantly more mechanical work than designed in Sweet Home, OR.
A torsion spring failure produces a sharp loud bang as the stored rotational tension releases at the fracture point in Sweet Home, OR. The bang is often heard throughout the home in Sweet Home. The door either drops if in motion or stays at its current position in Sweet Home, OR. The opener runs but the door won't follow in Sweet Home. Do not run the opener after a spring snap in Sweet Home, OR.
A broken torsion spring separates at the fracture point and creates a visible gap in the continuous coil in Sweet Home. The gap is typically one to three inches wide and is visible by looking at the spring on the shaft above the door in Sweet Home, OR. A visible gap means complete spring failure in Sweet Home. The door should not be operated until the spring is replaced in Sweet Home, OR.
A door that's noticeably higher on one side during operation has unequal spring tension or cable tension between the two sides in Sweet Home, OR. On a two-spring system, a spring that has lost tension on one side produces a door that rises unevenly in Sweet Home. Herlihy Garage Doors assesses spring condition on both sides when uneven door travel is reported in Sweet Home, OR.
Door height, width, steel gauge, insulation type, and window configuration assessed in Sweet Home, OR. Cable drum size confirmed in Sweet Home. Door weight estimated from the configuration factors in Sweet Home, OR. Complete picture of the door's weight and travel geometry confirmed before any spring is specified in Sweet Home.
Wire diameter, inside diameter, and length confirmed from the door assessment in Sweet Home. Correct winding turn count calculated from the door height and cable drum configuration in Sweet Home, OR. Replacement spring selected from vehicle inventory or ordered where a less common specification is required in Sweet Home.

Set screws tightened to correct specification in Sweet Home, OR. Cables reattached to drums with correct tension in Sweet Home.
Opener disconnected. Door manually lifted to halfway position in Sweet Home, OR. Door released and observed in Sweet Home. Holds at halfway — specification confirmed correct in Sweet Home, OR. Rises — oversprung, winding adjusted in Sweet Home. Drops — undersprung, winding adjusted in Sweet Home, OR. Opener reconnected only after balance test confirms correct specification in Sweet Home.
Both springs were installed at the same time and have completed the same number of cycles in Sweet Home, OR. Metal fatigue accumulates proportionally to cycles under stress in Sweet Home. The spring that broke reached its individual fatigue threshold first due to microscopic wire structure differences in Sweet Home, OR. The surviving spring is at essentially the same point in its fatigue progression in Sweet Home.
Replacing both springs during today's visit costs approximately $50 to $150 more than replacing only the broken spring in Sweet Home, OR. When the second spring breaks — and at the same fatigue progression it will — the cost is a second call-out charge, a second spring, and potentially a second after-hours charge in Sweet Home. The total of two separate repairs consistently exceeds the cost of replacing both during the original visit in Sweet Home, OR.
If the surviving spring was replaced recently and has significantly fewer cycles than the broken spring, replacing only the broken spring is the correct approach in Sweet Home. Herlihy assesses the surviving spring's age and specification and advises on the correct approach for the specific situation in Sweet Home, OR. Herlihy Garage Doors recommends replacing both springs when both are at the same fatigue progression in Sweet Home. The specific reasoning is explained clearly in Sweet Home, OR. The homeowner makes the final decision with complete information in Sweet Home. Herlihy never withholds the reasoning or pressures the outcome in Sweet Home, OR.
